T a/ZZ whom t may concern,.-

Beit known that I, J AMES MOORE, manager T. Robinson & Co.ProprietaryLimited, a subject of the King of Great Britain and Ireland,residing at Braeside, Railway Crescent, Elsternwick, in the BritishState of Victoria, Commonwealth of Australia, have invented certain newand `useful Improvements in Disk Plows, of which the following is aspecification. i

This invention relates to improvements in disk plows; and it consistsmainly in an improved framework therefor which, in addi- .tion to itsadaptability for quickly altering the width of the furrows, alwayspreserves and correctly maintains at any desired width of said furrowsthe proper line of draft, the improvements being equally applicableeither to a two-furrow low or to a plow for cutting a greater num er offurrows, while the other improvements consist in the means of supportingand adjusting the disks and to other combinations of parts hereinafterde scribed.

The invention will now be fully described, aided by a reference to theaccompanying sheet of drawings, in which-r Figure l is a perspectiveview of a disk plow embodying my improvements; Fig. 2, a plan view toclearly illustrate the adjustable framing which carries the disks; andFigs. 3 and 4 are side view and plan, respectively, of the frontfurrow-wheel bracket, while Figs. 5, 6, and 7 are side and end views andplan, respectively, of the adjustable bracket for supporting the disks.y

The framework comprises a system of parallel beams or bars, of whichthose marked A have their rear part bent at an angle of forty degrees,or thereabout, toward the disks B, which they support, while a shorterbar A supportsthe front furrow-wheel bracket or carrier C, and a longerbeam A4 carries the .hindmost disk and the back furrowfwheel. The beamsA and A are pivotally secured at their fore ends by bolts a to a bar A2,which lies obliquely over them, while at a short distance rearward andlying parallel with afore said oblique bar A2 are a pair ofover-and-under oblique beams A3, the angle of said h oblique beams A2and A3 being such as will allow for the forward advance of the line ofdisks B. Said disk beams A and A lie between and are pivotally securedby bolts a to the under and over oblique bars or beams A3.

The landside or rear disk beam A4 also lies parallel with beams A, andit also is pivotally connected by bolts a and a with the oblique beamsA2 and A3, while the front part of beam A4 extends in a direct lineforward to a position about transversely opposite to the end of thefront-wheel beam A, and the for ward end of both said beams A and A4 areconnected to atransverse bridle-bar A5, which stretches across the fullwidth in front of plow-frame and has an extension a2 pro-4 ris attached.The object of the projection a2 on the furrow side is to enable thedraftchain a3 to be hooked or shackled at a position well beyond thecenter line of draft in order to counteract against the landwardtendency of the rear disks. Alsoby the bridlebar Av being of such anunusual length and at such va forward position the p low is caused torun or work steadily and with less tendency to lift the disks B fromtheir working or cutting osition. The said bridle-bar A5 at both itsends has a series of holes a4 to secure the plow-frame at its desiredwidth and also to receive the shackles a5. D is a screwed adjusting-rodsecured by collars d to a bracket d, arranged on the landside-beam A4,while its screwed part takes into a swivel-nut d2, secured to theoblique beam A2, and D is a handle for rotating the screwed rod D andwhich latter is used for the purpose of adjusting the distance apart ofthe beams carrying the disks, and ,hence regulating the width of thefurrows, and which adjustment in the width of furrows may be from afraction of an inch to several inches.

By detaching the bridleebar from either or both bar A and beam A4 andthen rotating screw-threaded rod D inthe proper direction the inclinedor oblique beamsA2 A3 will be swung forwardly or rearwardly the desireddistance to bring the plow-bars A the re quired distance apart, andconsequently space the plows or disks B as desired. During thisadjustment the inclined beams swing on their pivotal connections withbeam A4 and also on the various bolts a a', and the plow-bars A aremaintained parallel with IOO each other and in the line of draft. Afterthe parts have been adjusted to bring the `glows B the desired distanceapart the brile-bar is again attached to the front ends of bars A andbeam A4. y

The vertical post of the rear furrow-wheel C2 is carried by abracketwhih is secured to the landside-beam A, while the vertical postof the front' furrow-wheel (y is supported by the bracket C, attached tothe off-side beam A/, and as said front and rear furrowwheel posts areconnected by levers they will always maintain a true draft line.

. The bracket C, which supports the post of the vfront furrow-wheel C',is provided with side lugs c,in which are slot-holes c, through whichbolts c2 pass for securing said bracket to the bar A ,and by said slotsc lying transverse to the line of draft the front furrowwheel can beadjusted to a greater or less width of furrow when necessary. Saidbracket is provided with an extension or foot piece c3, which restsonj'the front oblique beam A2 to maintain the vertical position of thefront furrow-wheel post.

The whole of thesystem of framework-bars (marked A to A5, respectively)are usually placed on the flat and not edgewise, as is the ordinarypractice in other plows. Further, the framework is `made preferably ofspringsteel,` the disks B being carried by cast-iron or other metalbearing-brackets E, in which the disk axles revolve, while saidbracketbearings are secured to the rear end parts of the beams A and tothe beam. A4. The said bearing-brackets E are so constructed that eachmay be adjusted to set the disks at the re uisite angle by Veachbracket-bearing being secured to the under side of the disk beams A andbeam A4 by two bolts e and e, the forward bolt e passing through a holein the beams and flange of lbearing-bracket E and the rear bolt epassing through a hole in the beam and through a radially-slotted holee2 inthe bearing-bracket E. The flange E of the bearing-bracket E israbbeted at e3 to permit of a stop-plate E2 being placed between therear part of the bearing-flange E and the beams A or the beam A4, saidplate E2 being serrated at c4 on its under side to receive an angularprojecting rib e5, formed on the rabbeted part of the ange EQ so thatwhen the bolts e and e are screwed up the bearing-bracket E will belocked securely at the desired position to suit the angle at which eachdisk B is to lie, the forward bolt e during the process of adjustmentacting as a pivot.
